The developing innervation of the chick eye has been studied using catecholamine histofluorescence. The innervation of the pupillary dilator by the superior cervical ganglion begins on day 13 of incubation when fluorescent axons can be seen in the ciliary zone circumscribing the dilator. On day 14 a few processes are seen to branch from this band into the dilator. The number of processes in the dilator increases on days 15 and 16. After day 16 there is a reorganization of the fibers radially accompanied by a moderate increase in the number of processes. In addition, a group of fluorescent cells can be seen in the choroid adjacent to the ciliary body. These cells are bipolar at day 9 and become multipolar by 12 days of incubation. These cells contribute to a fluorescent plexus of processes in the choroid which stops abruptly at the border of the choroid and ciliary zone. It is thought that they represent a terminal sympathetic ganglion receiving preganglionic input from the carotid nerve.
利用儿茶酚胺组织荧光法对鸡胚眼的神经支配发育进行了研究。颈上神经节对瞳孔开大肌的神经支配始于孵化第13天，此时在环绕瞳孔开大肌的睫状区可见荧光轴突。在第14天，可见一些突起从此带分支进入瞳孔开大肌。在第15天和第16天，瞳孔开大肌内的突起数量增加。16天后，纤维呈放射状重新排列，同时突起数量适度增加。此外，在靠近睫状体的脉络膜中可见一群荧光细胞。这些细胞在第9天为双极细胞，到孵化12天时变为多极细胞。这些细胞形成脉络膜内的一个荧光突起丛，该丛在脉络膜和睫状区的边界处突然终止。据认为，它们代表一个接受来自颈动脉神经节前输入的终末交感神经节。
